Iowa Admin. Code r. 441-200.4
The department shall not place a child in an approved adoptive home until parental rights of the child's birth parents have been terminated and guardianship assigned to the department. This would not apply to families and children participating in tribal customary adoption. If one or both birth parents are deceased, the worker shall provide the court with verification of the birth parents' death and the death shall be stated in the guardianship order. When the termination of parental rights is appealed by a birth parent, an adoptive placement may be made if the adoptive parents sign an adoptive placement agreement that includes an acknowledgment of the conditions of the placement should termination be overturned. However, the adoption may not be finalized until the appeal is withdrawn or a final decision regarding the appeal is reached and a procedendo issued.
